Engadget:

After AT&T decided to start rolling out “5G Evolution” branding on phones and networks that use 4G LTE Advanced technology, competitors have had to make decisions on how to respond. While T-Mobile mocked it with a sticker, Verizon (Engadget’s parent company) fired off a letter. So what is Sprint going to do? It has filed a lawsuit in federal court, seeking an injunction to prevent AT&T from using 5GE tags on its devices or advertising.

5GE is enhanced LTE, not 5G. That 5GE branding is consumer-hostile, at the very least.

From the AT&T Mobility Wikipedia page:

In 2017, AT&T began to similarly use the trademark 5G Evolution (5G E) to refer to LTE networks upgraded to support higher data speeds via LTE-Advanced and LTE Advanced Pro features, such as 4×4 MIMO antennas, 256-QAM, and three-way carrier aggregation. AT&T promotes these services as having a theoretical top speed of 400 Mbit/s. The suite is supported on certain high-end Android smartphones offered by the carrier, such as the LG V30 and the Samsung Galaxy S8 and S9, and the iPhone XR and XS. In late 2018, AT&T began to deploy software updates to display a “5G E” network indicator when connected to such a network.

This is a bad look, AT&T. Pull that 5GE from the status bar before your brand takes an even bigger hit.
